A Phase II Randomized, Observer-Blind, Multi-Center, Controlled Study of a Trivalent Group B Streptococcus Vaccine in Healthy Pregnant Women
The study investigated the immune response induced by the Group B streptococcus vaccine in healthy pregnant women. In addition, the study investigated the amount of vaccine induced antibodies which were transferred to the newborn.

Primary outcomes
- Geometric Mean Concentrations (GMCs) of Antibodies in Mothers and Infants at Delivery/Birth — Day of delivery/birth
GMCs of anti-Group B Streptococcus (GBS) capsular polysaccharide (CPS) antibodies against serotypes Ia, Ib and III in mothers and in infants at delivery/birth are presented. - Geometric Mean of the Ratios Between Infant Antibody Level (μg/mL) and Maternal Antibody Level (μg/mL) at Time of Delivery — Day of delivery/birth
The Geometric mean transfer ratio of anti-GBS CPS antibodies against serotypes Ia, Ib and III at delivery is calculated as the geometric mean of the pairwise ratios between the antibody concentrations from infant at birth and to maternal serum concentration at delivery.
